What this dot point is asking
This dot point asks you to explain user-centred design and apply it. User-centred design (UCD) is an approach that keeps the needs, behaviours and limitations of the actual users at the centre of every design decision, rather than the designer's own assumptions or preferences. You should understand what it means to design for real users, the idea of usability, tools such as personas and user testing, and the importance of accessibility. The core message is simple but powerful: design for the people who will use the thing, not for yourself, and check with them throughout.
The answer
What user-centred design means
User-centred design puts the user first at every stage. Instead of designing what the designer finds clever or attractive, the designer studies who the users are, what they need, how they behave, and what limits them, and uses that understanding to drive decisions. The user's needs, not the designer's taste, are the measure of success. This shift, from designing for yourself to designing for the user, is the heart of UCD and of modern design generally.
Understanding users
UCD begins with understanding real users through research: observing them, talking to them, and learning their goals, habits and frustrations. A useful tool is the persona, a realistic profile of a typical user (their needs, abilities and context) that the designer keeps in mind to stay focused on real people rather than a vague "average user". Understanding users prevents the common error of assuming everyone is like the designer.
Usability
Usability is how easy, efficient and satisfying a design is to use for its intended users. A usable product lets people achieve their goals quickly, with few errors and little frustration. Usability comes from clear, intuitive controls and layout (so users understand it without instructions), good feedback (the design responds clearly to actions), consistency, error prevention, and simplicity. Usability is the practical test of whether a design truly serves its users.
Accessibility
User-centred design considers the full range of users, including people with different abilities, ages and circumstances. Accessibility means designing so that as many people as possible can use the design, including those with visual, hearing, physical or other impairments. Designing for accessibility (high contrast, clear type, alternatives to sound, easy physical use) often improves the design for everyone, not just those with specific needs. Ignoring accessibility excludes real users.
Testing and feedback
Because the user is central, UCD relies on involving users throughout, especially through testing. Designers test prototypes with real users, observe what works and what does not, gather feedback, and refine the design, repeating the cycle. This keeps the design grounded in real behaviour rather than the designer's guesses, and it is how usability problems are found and fixed. User-centred design and the iterative design process go hand in hand.
Examples in context
Example 1. A well-designed app. An app that new users can navigate without instructions, with obvious controls, clear feedback and accessible text sizes, reflects user-centred design. Its ease of use comes from research and testing with real users, showing usability as the practical result of putting users first.
Example 2. A redesigned medicine label. A medicine label redesigned after watching elderly patients struggle, with larger type, clearer instructions and a logical order, helps users take medication correctly. The design grew from understanding real users' difficulties, illustrating how user-centred research leads to a safer, more usable result.
Try this
Cue. Find a product or app you find easy to use and one you find frustrating. For each, identify two usability features (or failures) and explain how they affect the user's experience.
Cue. Write a short persona for a user of a design of your choice: their needs, abilities and context. Explain one design decision you would make differently because of this persona.
Cue. Choose a confusing everyday design (a sign, a remote, a form) and describe how you would improve it using user-centred design: research the users, design for usability and accessibility, and test with real people.

Original6 marksExplain what user-centred design means and describe three ways a designer can keep the user's needs at the centre of a project.Show worked answer →
User-centred design means designing with the needs, behaviours and limitations of the actual users as the central focus, rather than the designer's own preferences. The user comes first at every stage.
Three ways to keep the user central:
Research the users. Observe and talk to real users to understand their needs, behaviours and frustrations before designing.
Involve users through testing. Test prototypes with real users and use their feedback to improve the design, repeating as needed.
Design for usability and accessibility. Make the design easy and comfortable to use for the full range of intended users, including those with different abilities.
What markers reward: a correct definition (designing around real users' needs, not the designer's preferences), and three valid practices such as researching users, testing with users, and designing for usability and accessibility.
Original4 marksExplain what 'usability' means and give two features that make a product more usable.Show worked answer →
Usability is how easy, efficient and satisfying a product is to use for its intended users. A usable product lets people achieve their goals quickly, with few errors and little frustration.
Two features that improve usability:
Clear, intuitive controls or layout - users can understand how to use it without instructions, for example obvious buttons or a logical menu.
Good feedback - the product responds clearly to actions, for example a button that visibly reacts when pressed, so users know what is happening.
Other valid features: error prevention, consistency, and accessibility.
What markers reward: a correct definition of usability (ease, efficiency and satisfaction of use), and two genuine features that make something easier to use.
